To all-whom it may concern.:

Be it known that I, EGBERT H. GOLD, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Attachments for Heating Systems, of which the following is a .specifi` cation. This invention relates to improvement-s in fluid heating apparatus and, is particularly adapted for use in conjunction with the steam supply of a car-heating system, or other fluid distri uting system, wherein it is desirable that no condensed [luid be permitted to remain inthe radiating or other pipes after the su ly of steam has been shut ofi.

e object of my invention is to provide means by the use of which the condensed fluid is ermitted to drip from a waste or outlet pipe but is not permitted to become frozen as it drips from said ipe and thereby close the latter.V This and) such other objects as may hereinafter appear are accomplished in the device illustrated inh the accompanying drawings, in which- Figure'l is an elevational view of apparatus illustrating my invention; and Fig. 2 shows a cross-section taken on the line 2-2 of Fig. 1 looking downward.

In the several figures of the drawing, A is the door of a car, B is an inlet or feed ipe which takes steam or other heating iuid from the train pipe. This pipe B communicates through an elbow C and short pipe D with the valve casing E.

The valve casing may contain a valve of the form shown in my co-pending' application Serial No. 291,759, or said valve may bp of any desired forni by means of which means are provided for cstablishin communication between the feed pipe and t ie radiating system when the valve is open while, when the valve is closed andthe sup ly of fluid shut oil', communication is esta lished between the radiating system and the atmosphere; so4 that fluid condensing in the radiating system may find its way out of the same. Any form of valve may be employed which effects this result, but the valve herein shown and more fully described in thc co-pending application referred to has been found to be well suited to this purpose.

In practice it has been found that one of the dillicultics to be overcome is that of preventing the freezing in the drip pipe of the fluid which condenses in the radiatin system and finds its way out through sai drip pipe. Such freezing, .of course, clogs the drip pipe, or even closes the saine wholly. Fis t 1e pipe leading from the valve casing toy 69 the radiating system and G the drip pi e leading downward from the valve E. Tlie means by which I overcome the objection referred to is that of providing a heat conducting member adaptedl to embrace the steam supply pipe and the drip pipe, so that the dri pipe will be kep't warm by conduction of eat from the hot steam pipe thereto.

In the form of my invention which is illustrated in the drawings I provide a pair of Toke members H and I, these members being nged together at J. The yoke members are of such a form that each pipe is practically com letely inclosed in the metal of the yokes. Flach of the yoke. members is perforated at its end opposite the end which is hinged to the other yoke member. Throu h these erforated ends is passed a bolt which is provided with a mit L, by the tightening of which the yoke members are drawn 3g, into firm Contact with the feed pipe and drip i e. P IIn installing heating apparatus in cars it is important that suoli a connection as is herein A shown shall be adjustable, for the reason that 35 the various pipes and attachments found beneath the carand between its floors vary so in diilerent cars. For example, the pipes B and F may approach their connections at different angles from those shown in Fig. 1 of 90 the drawings. This will necessitate arrangements of pipes G and D in a variety of different positions relative to cach other and involves the construction of the connection between the feed pipe and the drip pipe so g5 that it may be accommodated for different relative positions of these pipes.

In practical construction I preferably provide the elbow C, and by making it very heavy and litt-ing the yoke members around this elbow I obtain the most ellicient heat retaining and heat conducting device, and I prefer in such construction that the elbow shall be formed with a wide neck M at one of its ends adapted to be closely embraced by the yoke members Hand I. Obviously, however` it is of secondary importance as to what part of the feed pipe is engaged by the yoke members and the relative weight of the yoke members and parts to which they are 110 attached is a matter of choice to snit varying conditions.

I prefer to thread the upper ends of the pipes G and D or otherwise provide` for a con nection between these pipes and the valve casing E wMch will permit their rotation.

In Fig. 2 I have shown in full lines the supply pipe B approaching from one direction and in dotted lines the Same approaching from another direction, and I have also illustrated in dotted lines one of various alternative positions of the drip pipe G with reference to the vertical portion D of the feed pipe.

It will be seen that generically my invention contempiates the use of means formed of metal, or other good heat conducting mate rial, adapted to embrace the supply pipe of a inid heating system and the waste pipe which carries oit the condensation from-said system, whereby the -waste pipe is heated and the products of condensation prevented from becoming frozen and obstructing said waste pipe.

This is a division of my co-pending application Serial \`o. 201,75), filed December 14,

I claim:

1. The combination with a casing, of a. pipe leading from the valve casing and adapted to be connected with a radiating system, a drip pipe leading from said casing,a feed pipe, a pipe connection extending from the casing to the feed pipe and comprising an elbow to connect the same with the feed pi ie, apart of said connection being rotatable reiative to the casing, and removable yoke meml bers engaging the lower end of said connection and the drip pipe all arranged so as to l accommodate for dill'crcnt angular positions l of the feed pipe and the pipe leading to the l radiating system.

2. The combination with a valve casing, of a pipe leading from seid casing and adapt. ed to )e connected with a radiating system, a drip pipe leading from the valve casing, a fced pipe, a pipel connection leading from the.

being connected with the valve casing b v a joint permitting its rotation with respect thereto, and removable yoke members engaging with the lower end ol said connection and withsaid drip pipe, all arranged so as to accommodate for different angular positions of the feed pipe and the pipe leading to the radiating s vstcm.v y

3. The combination with a valve casing, of a pipe leading from the valve casing and adapted te be connected to the radiating system, adrip pipe leading from said valve casing, a feed pipe, an elbow connected with the elbow tothe valve casing, said connecting )ipe connected with the valve casing by a )omt permitting its rotation, and removable vokc members connecting the elbow with the. drip pipe, all arranged so as to accommodate for ditcrent angular positions of' thc. fce.d pipe and the. pipe. leading to tho radiating system.
